Los Angeles Department of Water and Power

The Los Angeles Department of Water and Power (LADWP) is the largest municipal utility in the United States, serving over four million residents. It was founded in 1902 to supply water and electricity to residents and businesses in Los Angeles and surrounding communities.

Service territory
In addition to the city of Los Angeles, LADWP also provides services to these communities:
 * Bishop (parts of)
 * Culver City (parts of)
 * South Pasadena (parts of)
 * West Hollywood (parts of)

Power system
The LADWP currently maintains a generating capacity of 7,000 to serve a peak demand of 5,600 megawatts. According to the LADWP website, the power mix consists of coal (50 percent), natural gas (25 percent), large hydro (11 percent), nuclear (12 percent) and renewable power (2 percent). However, according to figures for 2010, the amount of electricity generated by coal-fired power plants had been reduced to 39%. Natural gas accounted for 31% and nuclear accounted for 9%. Solar accounted for less than 1%.

The LADWP, along with the California Department of Water Resources, also operates the Castaic Pumped Storage Power Station as a pumped storage facility. Water flows from the upper reservoir to the lower during the day, generating power when demand is highest, and is pumped back up at night when excess capacity is available. About 1,600 megawatts, or 22% of the total capacity, is generated at this facility alone. The Los Angeles City Council voted in 2004 to direct the LADWP to generate 20% of its energy (excluding Hoover Dam) from clean sources by 2010. Current "green power" sources account for 5% of the LADWP's capacity, but there are plans to add a 120 megawatt wind farm in Tehachapi, California, and produce electricity from geothermal sources in the Salton Sea area and photovoltaic sources.

2010 Integrated Resource Plan calls for phasing out coal
The 2010 Integrated Presource Plan, a strategic plan for the next 20 years, recommended that LADWP add 630 new megawatts of solar capacity by 2020 and 970 megawatts of solar capacity by 2030. The plan recommended 580 megawatts of new wind power by 2020. The plan designated that 40 percent of solar be in-basin. It recommended incentive programs, feed-in tariff schemes, and other mechanisms for promoting solar. The plan recommended ending purchases of power from the coal-fired Navajo Generating Station by 2014, which is five years ahead of the deadline established by California state law. The plan recommends ending use of power from the coal-fired Intermountain Power Station by 2020, seven years ahead of the scheduled end of such purchases. The plan states that "LADWP is open to a mutually agreeable early compliance plan between the project participants that preserves the site and transmission for clean fossil and renewable generation."
